Problems solved by technology

Some methods for solidifying molasses have been disclosed. For example, Chinese patent CN 102321770 "Preparation method of full-nutrition solid sugarcane molasses" discloses a method of directly putting liquid molasses into a vacuum dryer without any pretreatment. And remove moisture under vacuum condition, pulverize after cooling to obtain the method for powdery full-nutrition solid sugarcane molasses, yet, this method usually needs 2-5 hour drying time, and drying time is longer and energy consumption is higher, needs to increase after drying The crushing section may cause product loss. In addition, the prepared molasses powder is easy to agglomerate during storage; also for example, Chinese patent CN102160598 "a preparation method for solid molasses" discloses a method of adding 20- 25% calcium hydroxide is used as a carrier, and then dried and ground to make powdered solid molasses. However, the granulation time of this method is 2-5 hours, and the drying also takes 2-5 hours, which takes a long time , the calcium hydroxide used itself has no nutritional value, and is alkaline and has a certain degree of corrosiveness; another example, Chinese patent CN 103549196 "A kind of pelleted feed for cattle and sheep and its preparation method" discloses a feed pelleted by a flat die. Mechanism granulation is a method of mixing molasses with elephant grass, cassava residue, etc. to obtain pellet feed for cattle and sheep. However, the proportion of molasses added in this method is not high, and the particle size is relatively large, and it can only be eaten by ruminants such as cattle and sheep. narrow range of applications
[0006] Based on the problems existing in the above-mentioned prior art, the applicant envisages using commonly used feed materials as the carrier, using molasses as the binder, and mixing and granulating through an appropriate process, so as to immobilize the liquid form of molasses, which can not only solve the problem of Liquid molasses is difficult for long-distance transportation and storage, and the obtained immobilized molasses can also be used as a raw material to prepare full-price feed suitable for various poultry and livestock

preparation example Construction

[0050] In one aspect, the present invention relates to a kind of preparation method of molasses solid-carried feed, described method comprises the following steps:

[0051] (1) Pretreatment: molasses is concentrated and preheated;

[0052] (2) Granulating: the carrier material is placed in a granulator equipped with a bottom mixing paddle and a side pulverizing paddle, and the preheated molasses is continuously sprayed into the granulator for granulation to obtain wet granules;

[0053] (3) Optionally, drying and cooling the wet granules obtained in step (2) to obtain dry granules;

[0054] (4) Classification: classifying the wet granules in step (2) or the dry granules in step (3) to obtain molasses immobilized feed.

[0055] In step (1) of the present invention, various methods known in the art can be used to concentrate the molasses to a suitable Brix value. When the Brix value was too low, the water content in the molasses was higher, thereby affecting the carrier's abili...

Embodiment 1

[0068] The molasses immobilized beet meal powder particles were obtained through the following steps:

[0069] (1) Pretreatment: take the molasses after sugar production, undergo evaporation and concentration treatment, concentrate to a Brix value of 73, and then preheat to 40°C before granulation;

[0070] (2) Granulation: Select dry sugar beet meal powder as the carrier raw material, put it into the cavity of the granulator equipped with bottom mixing paddle and side pulverizing paddle in advance, and spray the preheated molasses into it continuously through the top of the peristaltic pump Granulate in the granulator, the rotating speed of the bottom mixing paddle is 500r / min, the shear speed of the side pulverizing paddle is 2500r / min, and the final addition ratio of molasses and beet meal powder is 1:1;

[0071] (3) The obtained molasses-immobilized sugar beet meal has fine particles, uniform color distribution, looseness, good fluidity and is not easy to harden (such as ...

Embodiment 2

[0076] Obtain molasses immobilized wheat bran particles through the following steps:

[0077] (1) Pretreatment: take the molasses after sugar production, undergo evaporation and concentration treatment, concentrate to a Brix value of 75, and then preheat to 50°C before granulation;

[0078] (2) Granulation: Wheat bran is selected as the carrier raw material, which is pre-placed into the cavity of the granulator equipped with bottom mixing paddles and side pulverizing paddles, and the preheated molasses raw material is continuously top-sprayed into the granulation through a peristaltic pump Granulate in the machine, the rotating speed of the bottom mixing paddle is 600r / min, the shear speed of the side pulverizing paddle is 3000r / min, and the final addition ratio of molasses and wheat bran is 2:3;

[0079] (3) The obtained molasses immobilized feed is delicate, uniform, loose, has good fluidity and is not easy to harden, therefore, it can enter the next step without drying;

Abstract

The present invention provides a preparation method and storage method of molasses immobilized feed and the molasses immobilized feed obtained therefrom. The preparation method includes pretreatment, granulation, optional drying step and grading step; the The storage method includes a packaging step and a storage step. The present invention also provides the molasses immobilized feed prepared by the above method, which not only solves the problems of long-distance transportation of liquid molasses and difficulty in adding it to the feed, but also provides an effective way to directly feed livestock or prepare full-price feed as a raw material. for convenience.

Description

technical field [0001] The present invention relates to the fields of sugar industry and feed processing. Specifically, the present invention relates to a method for producing molasses immobilized feed by using molasses and a carrier, and the molasses immobilized feed obtained by the method. Background technique [0002] my country is one of the largest sugar producing and consuming countries in the world, and the sugar industry occupies an important position in the national economy. Molasses is a by-product of the sugar industry. It is a viscous, dark brown, semi-fluid liquid. Its composition will vary slightly due to different sugar raw materials and processing conditions. As a raw material, molasses is widely used in feed, chemical, food, light industry and pharmaceutical industries. [0003] The main component of molasses is sugar, including sucrose, glucose and fructose. The general sugar content (calculated as sucrose) is between 40-56%. The molasses contains 3%-6% cr...
